(8) Convenient stud mounting hole facilitates cutting studs to specified lengths
The stud mounting hole is very convenient when cutting many studs to the same length at floor level. The
adjustable stud mounting hole permits mounting of M6 to M10 studs, and can be used as an accurate cutting
length guide for the full range of applicable studs. It can be used not only to align cutting lengths to the rear of the
main body, as shown in Fig. 12-(1), but also to align cutting lengths to the front of the main body, as shown in
Fig. 12-(2). The stud mounting hole is particularly convenient when it is necessary to cut several studs at the
same length from, for example, the surface of a ceiling.

(9) Cam-operated auto-return mechanism
After cutting, the cutter is forcibly returned (opened) by means of a plate cam commonly called a "return plate".
This mechanism prevents such malfunctions as the cutter becoming jammed and not returning.
